Description

Technical Field

[0001] The present invention relates to the technical field of intelligent learning machine assembly, and more specifically, to an assembly jig for an intelligent learning machine. Background Art

[0002] The full name of the intelligent learning machine is the intelligent learning device. Its shape is similar to a tablet, and it is composed of an upper cover plate, a lower cover plate, a circuit board, and a display screen. Currently, when assembling the intelligent learning machine, the circuit board and the display screen are installed on the lower cover plate, and then the upper cover plate is installed on the lower cover plate by stamping, so that the buckles on the upper cover plate and the lower cover plate are snapped together, thus completing the encapsulation of the cover plate.

[0003] Currently, the following problems exist in the process of assembling the upper cover plate and the lower cover plate: ①. When encapsulating the upper cover plate, since the upper cover plate needs to place the display screen, it is mainly a frame structure, and the area of its structure is small, making it rather troublesome to position the upper cover plate. ②. When pressing, a horizontal pressing method is adopted. When installing, the buckles on the upper cover plate and the lower cover plate are snapped together at the same time. During this process, it is easy for several buckles to be misaligned and unable to be snapped together. ③. When all the buckles are snapped together, before the buckle enters the card slot, the buckle will push the side wall with the card slot, causing the side wall with the card slot to be dented. For a metal cover plate, it is easy for the cover plate to be bent, resulting in the buckle and the card slot being unable to be snapped together. Summary of the Invention

[0004] The purpose of the present invention is to provide an assembly jig for an intelligent learning machine to solve the problem of the combination of the upper cover plate and the lower cover plate proposed in the above background art.

[0005] To achieve the above object, an assembly jig for an intelligent learning machine is provided, including a mounting frame. A receiving seat is fixed on the upper side of the mounting frame. An upper mold is arranged on the upper side of the receiving seat, and the upper mold positions the lower cover plate of the intelligent learning machine. A lower mold is arranged inside the receiving seat, and the lower mold positions the upper cover plate of the intelligent learning machine. A rotating lifting member is arranged on the lower side of the lower mold, and the rotating lifting member is rotatably arranged with the receiving seat; The rotating lifting member pushes one end of the lower mold upward, making the lower mold in an inclined state in the receiving seat. At the same time, when the lower mold is in an inclined state, the rotating lifting member pushes one end of the upper cover plate upward. When the upper mold presses down on the lower mold, the lower mold rotates into the interior of the receiving seat. At the same time, during the downward movement of the lower mold, the rotating lifting member gradually releases the pushing force on the upper cover plate, enabling the upper cover plate to completely enter the interior of the lower mold. During the process of the upper mold pressing the lower mold into the interior of the receiving seat, the lower cover plate and the upper cover plate are gradually snapped and fixed from one end to the other end; After the upper cover plate and the lower cover plate are installed, the upper die moves upward away from the lower die. At this time, the rotating lifting member jacks up the lower die upward, and during the process of the rotating lifting member jacking up the lower die, the rotating lifting member also jacks up the lower cover plate upward.

[0006] As a further improvement of this technical solution, the receiving seat includes a bottom die shell, a die placing cavity is formed on the upper side of the bottom die shell, the lower die includes a lower die block, the lower die block is arranged inside the die placing cavity, and the upper end of one side of the lower die block and the position near the top of one side of the bottom die shell are hinged. An inclined receiving surface is arranged at one end of the die placing cavity away from the hinge with the lower die block, and an inclined surface adapted to the receiving surface is arranged at the position of the lower die block close to the receiving surface. When the lower die block is horizontally arranged in the die placing cavity, the side wall of the lower die block is in close contact with the side wall of the die placing cavity.

[0007] As a further improvement of this technical solution, a cover placing cavity is arranged on the upper side of the lower die block, the upper cover plate is arranged upside down in the cover placing cavity, the upper die includes an upper die block, a pressing groove is formed at the bottom of the upper die block, the edge of the lower cover plate is arranged in the pressing groove, and a suction cup is arranged on the upper side of the pressing groove. The suction cup fixes the position of the lower cover plate in the pressing groove by suction.

[0008] As a further improvement of this technical solution, a pressing groove is formed at the position on the upper side of the lower die block away from the hinge with the bottom die shell, and a pressing strip is fixed at the position corresponding to the pressing groove on the lower side of the upper die block. During the downward movement of the upper die, the pressing strip first contacts the side wall of the pressing groove, and then the lower die block rotates downward around the position hinged with the bottom die shell through the pressing of the pressing strip on the pressing groove.

[0009] As a further improvement of this technical solution, the rotating lifting member includes a rotating column, a plurality of sliding plates are fixed on the lower side of the rotating column, a rotating plate, a height limiting plate and a thrust adjusting plate are sequentially arranged from top to bottom on the lower side of the rotating column. The lower end of the sliding plate sequentially slides through the rotating plate, the height limiting plate and the thrust adjusting plate, and a baffle is fixed at the position where the sliding plate penetrates the lower end of the thrust adjusting plate.

[0010] As a further improvement of this technical solution, a groove corresponding to the lower side shape of the rotating plate is formed on the upper side of the height limiting plate. The height limiting plate is fixed on the sliding plate by screws. The height limiting plate controls the upward movement distance of the sliding plate. A pushing mechanism is arranged between the thrust adjusting plate and the height limiting plate, and the pushing mechanism drives the height limiting plate and the sliding plate to move upward.

[0011] As a further improvement of this technical solution, both ends of the rotating plate are rotatably connected to mounting shells through pin shafts. A rotating groove is formed on the side of the mounting shell away from the rotating plate. A rotating rod is arranged in the rotating groove. The rotating rod is fixedly connected to the pin shaft. Both ends of the thrust adjusting plate are slidably arranged on the rotating rod, and the thrust adjusting plate is fixed to the rotating rod by screws.

[0012] As a further improvement of this technical solution, a flipping groove is formed at the bottom of the die placing cavity. A blocking groove penetrating the bottom of the bottom die shell is formed below the flipping groove. Mounting openings are arranged at both ends of the flipping groove. The mounting shell is fixed in the mounting openings. The rotating plate is arranged in the flipping groove. There is a gap between the outer side wall of the height limiting plate and the side wall of the blocking groove. A limiting groove is formed at the position corresponding to the flipping groove on the lower side of the lower module. A rotating groove is arranged above the limiting groove. The rotating column is rotatably arranged in the limiting groove. There is a gap between the limiting groove and the sliding plate.

[0013] As a further improvement of this technical solution, the pushing mechanism pushes the height limiting plate and the rotating column upward. The upward moving rotating column jacks up the lower module, causing the lower module to rotate upward around the position hinged to the bottom die shell, so that the upper surface of the lower module is in an inclined state. During the rotation of the lower module, the rotating column drives the rotating jacking member to rotate around the axis of the pin shaft.

[0014] As a further improvement of this technical solution, a plugging groove is arranged above the rotating groove. A jacking mechanism is fixed inside the plugging groove. The jacking mechanism includes a jacking plate slidably arranged in the plugging groove. A buckling groove is formed on the side of the cover placing cavity close to the pressing groove. One end of the jacking plate penetrates the side wall of the plugging groove and extends into the buckling groove. An arc groove is formed on the arc-shaped side wall of the rotating column. One end of the arc groove is close to the axis of the arc groove and the other end is far from the axis of the arc groove. One end of the jacking plate is slidably arranged in the arc groove. When the rotating jacking member jacks up the lower module, the jacking plate jacks up one end of the upper cover plate in the cover placing cavity upward. When the lower module is horizontally arranged, the jacking plate does not push the upper cover plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the assembly jig of this intelligent learning machine, by installing the upper cover plate on the lower die and the lower cover plate on the upper die, the positioning of the upper cover plate is facilitated, and the installation between the upper cover plate and the lower cover plate is convenient. At the same time, the edge of the lower cover plate contacts the upper die, and the middle part of the lower cover plate is adsorbed by a suction cup, so that when the lower cover plate is clamped with the upper cover plate, the middle part of the lower cover plate will not press the circuit board and display screen in the upper cover plate, ensuring the effective clamping between the upper cover plate and the lower cover plate.

[0016] 2. In the assembly jig of the intelligent learning machine, one end of the lower mold is jacked up by the rotating jacking member, so that the upper cover plate received by the lower mold is in an inclined state. When the upper mold drives the lower cover plate to move downward, one end of the lower cover plate first contacts one end of the upper cover plate. As the upper mold continuously moves downward to extrude the lower mold, the lower mold gradually tends to be in a horizontal state. During the process of the lower mold tending to be in a horizontal state, the lower cover plate and the upper cover plate are clamped together. Through the progressive clamping design (clamping from one end to the other end in sequence), the assembly stress can be evenly dispersed, avoiding the situation that the cover plates are sunken and bent due to instantaneous multi-point clamping on the upper cover plate and the lower cover plate, and ensuring the clamping effect of the upper cover plate and the lower cover plate.

[0017] 3. In the assembly jig of the intelligent learning machine, one end of the upper cover plate is jacked up by the provided jacking mechanism. When the lower mold is inclined, the jacking mechanism jacks up the upper cover plate, making it convenient for the staff to pick up and place the upper cover plate. When the upper cover plate and the lower cover plate are all clamped, the jacking mechanism does not jack up the upper cover plate, thus facilitating the picking up and placing of the cover plates and reducing the trouble of the staff in assembling the cover plates.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] Embodiment 1 At the positions near the edges of the upper cover plate and the lower cover plate of the intelligent learning machine, clamping edges will be provided. On the clamping edges of the upper cover plate and the lower cover plate, a clamping groove and a clamping buckle will be respectively provided. When the upper cover plate and the lower cover plate are clamped, the clamping buckle is clamped in the clamping groove to complete the assembly of the upper cover plate and the lower cover plate.

[0023] When encapsulating the upper cover plate, since the upper cover plate needs to place a display screen, it is mainly a frame structure with a small structural area, and it is rather troublesome to position the upper cover plate; When pressing, a horizontal pressing method is adopted. When installing, the clamping buckles on the upper cover plate and the lower cover plate are clamped at the same time. During this process, it is easy for several clamping buckles to be staggered and unable to be clamped; When all the clamping buckles are clamped together, when the clamping buckle has not entered the clamping groove, the clamping buckle will push the side wall with the clamping groove, causing the side wall with the clamping groove to be recessed. For a metal cover plate, it is easy to cause the cover plate to be bent and the clamping buckle and the clamping groove to be unable to be clamped together.

[0024] To solve the above problems, the purpose of this embodiment is to provide an assembly jig for an intelligent learning machine. Please refer to Figures 1-5 As shown, it includes an installation frame 1. The installation frame 1 is installed on the workbench of the stamping machine by screws. Here, the stamping machine is a common hydraulic stamping machine on the market, which mainly includes a machine body and a hydraulic rod. The installation frame 1 is installed on the workbench of the machine body. A receiving seat 2 is fixed on the upper side of the installation frame 1. An upper mold 4 is arranged on the upper side of the receiving seat 2. The upper mold 4 is installed on the piston rod of the hydraulic rod. The upper mold 4 positions the lower cover plate of the intelligent learning machine. A lower mold 3 is arranged inside the receiving seat 2. The lower mold 3 positions the upper cover plate of the intelligent learning machine. A rotating jacking member 5 is arranged on the lower side of the lower mold 3. The rotating jacking member 5 is rotatably arranged with the receiving seat 2; The rotating jacking member 5 pushes one end of the lower mold 3 upward, causing the lower mold 3 to be in an inclined state in the receiving seat 2. When the lower mold 3 is inclined, the upper cover plate on the upper side of the lower mold 3 is also in an inclined state. At the same time, when the lower mold 3 is in an inclined state, the rotating jacking member 5 pushes one end of the upper cover plate upward, causing one end of the upper cover plate to be jacked up. When the upper mold 4 is driven by the piston rod to press down on the lower mold 3, the upper mold 4 presses the lower mold 3 downward, causing the lower mold 3 to rotate inwardly towards the receiving seat 2. At the same time, during the downward movement of the lower mold 3, the rotating jacking member 5 gradually releases the pushing force on the upper cover plate, allowing the upper cover plate to fully enter the interior of the lower mold 3. During the process of the upper mold 4 pressing the lower mold 3 into the interior of the receiving seat 2, the lower cover plate and the upper cover plate are gradually clamped and fixed from one end to the other end. By gradually clamping the lower cover plate and the upper cover plate from one end to the other end, it is possible to avoid local stress concentration and depression of the cover plate caused by all the buckles being clamped at once, thereby improving the clamping effect between the lower cover plate and the upper cover plate.

[0025] After the upper cover plate and the lower cover plate are installed, the upper mold 4 moves upward away from the lower mold 3. At this time, the rotating jacking member 5 jacks the lower mold 3 upward, and during the process of the rotating jacking member 5 jacking the lower mold 3, the rotating jacking member 5 also jacks the lower cover plate upward, making it convenient for the operator to take out the installed intelligent learning machine.

[0026] The structures of the receiving seat 2, the lower mold 3, the upper mold 4, and the rotating jacking member 5 are refined as follows: Refer to Figures 7-9 , the receiving seat 2 includes a bottom mold shell 21, the bottom mold shell 21 is square, and a mold placement cavity is provided on the upper side of the bottom mold shell 21. The lower mold 3 includes a lower module 31, and the lower module 31 is arranged inside the mold placement cavity. One end of the upper side of the lower module 31 is hinged to a position near the top of one side of the bottom mold shell 21. An inclined receiving surface 24 is provided at one end of the mold placement cavity away from the hinge with the lower module 31. A slope adapted to the receiving surface 24 is provided at a position of the lower module 31 close to the receiving surface 24. When the lower module 31 is horizontally arranged in the mold placement cavity, the side wall of the lower module 31 is in close contact with the side wall of the mold placement cavity. After the side wall of the lower module 31 is in contact with the side wall of the mold placement cavity, the lower module 31 is blocked by the mold placement cavity, making it impossible for the lower module 31 to rotate downward. At this time, the lower module 31 is in a horizontal state. A cover placement cavity is provided on the upper side of the lower module 31, and the upper cover plate is arranged upside down in the cover placement cavity. When the lower module 31 is horizontally arranged, the upper cover plate placed in the lower module 31 is also in a horizontal state.

[0027] Refer to Figure 14 and Figure 15As shown, the rotating lifting member 5 includes a rotating column 51. Below the rotating column 51, a rotating plate 52, a height limiting plate 53, and a thrust adjusting plate 54 are sequentially arranged from top to bottom. On the upper side of the height limiting plate 53, a groove corresponding to the shape of the lower side of the rotating plate 52 is provided. The rotating plate 52 can be closely attached to the groove on the upper side of the height limiting plate 53. At the same time, several sliding plates 512 are fixed to the lower side of the rotating column 51. The lower ends of the sliding plates 512 sequentially slide through the rotating plate 52, the height limiting plate 53, and the thrust adjusting plate 54. And a baffle is fixed at the position where the sliding plate 512 passes through the lower end of the thrust adjusting plate 54. The baffle can prevent the sliding plate 512 from slipping off the thrust adjusting plate 54, so that the rotating plate 52, the height limiting plate 53, and the thrust adjusting plate 54 can all slide stably on the sliding plate 512.

[0028] The height limiting plate 53 is fixed to the sliding plate 512 by screws. When the rotating column 51 moves away from the rotating plate 52, when the height limiting plate 53 contacts the rotating plate 52, the height limiting plate 53 controls the upward movement distance of the sliding plate 512. At the same time, a pushing mechanism is arranged between the thrust adjusting plate 54 and the height limiting plate 53. The pushing mechanism drives the height limiting plate 53 and the sliding plate 512 to move upward, so that the rotating column 51 moves away from the rotating plate 52. At both ends of the rotating plate 52, mounting shells 55 are rotatably connected by pin shafts. On the side of the mounting shell 55 away from the rotating plate 52, a rotating groove is provided. A rotating rod 56 is arranged in the rotating groove. The rotating rod 56 is fixedly connected to the pin shaft. One end of the rotating rod 56 can rotate in the rotating groove. After the rotating rod 56 rotates a certain angle, it will contact the side wall of the mounting shell 55. The mounting shell 55 blocks the rotation of the rotating rod 56 and limits the rotation angle of the rotating rod 56.

[0029] On the side where the two rotating rods 56 are close to each other, sliding grooves 561 are provided, and sliding blocks are fixed at both ends of the thrust adjusting plate 54. The two ends of the thrust adjusting plate 54 are slidably arranged on the rotating rods 56, that is, the sliding blocks are slidably arranged inside the sliding grooves 561. Through the sliding restriction between the sliding blocks and the sliding grooves 561, the thrust adjusting plate 54 can move along the axis direction of the rotating rod 56. At the same time, mounting plates are screwed to both ends of the thrust adjusting plate 54. The mounting plates are arranged on the side of the rotating rod 56 away from the sliding grooves 561, and screws are provided on the mounting plates. When the screws are tightened, the thrust adjusting plate 54 is fixed to the rotating rod 56 by screws.

[0030] The pushing mechanism includes two sliding rods 58 that slide through the thrust adjusting plate 54. The sliding rods 58 are in the same axial direction as the sliding plate 512. One end of the sliding rod 58 is threadedly fixed to the side of the height limiting plate 53 close to the thrust adjusting plate 54. And between the height limiting plate 53 and the thrust adjusting plate 54, two top push springs 57 sleeved on the sliding rods 58 are provided. The top push springs 57 push the thrust adjusting plate 54 and the height limiting plate 53 away from each other. Refer toFigures 8-9 At the bottom of the die placing cavity, a flipping groove 22 is formed. The flipping groove 22 communicates with the die placing cavity. At the lower side of the flipping groove 22, a blocking groove 23 penetrating the bottom of the bottom die shell 21 is formed. The blocking groove 23 is in the shape of a trumpet with a narrow upper part and a wide lower part. Installation openings 25 are arranged at both ends of the flipping groove 22. The installation openings 25 are formed in the bottom die shell 21. The installation shell 55 is fixed in the installation openings 25 by screws. The rotating plate 52 is arranged in the flipping groove 22. There is a gap between the outer side wall of the height limiting plate 53 and the side wall of the blocking groove 23. The gap between the height limiting plate 53 and the blocking groove 23 is provided to enable the height limiting plate 53 to swing in the blocking groove 23.

[0031] In order to enable the rotating jacking member 5 to stably support the lower module 31 for tilting, refer to Figures 10-12 At the position corresponding to the flipping groove 22 on the lower side of the lower module 31, a limiting groove 35 is formed. Above the limiting groove 35, a rotating groove 34 is provided. The rotating groove 34 is a cylindrical groove, and its shape is adapted to the rotating column 51. The rotating column 51 is inserted into the inside of the limiting groove 35 from one end of the rotating groove 34, so that the rotating column 51 is rotatably arranged in the limiting groove 35. The sliding plate 512 is arranged in the limiting groove 35. There is a gap between the limiting groove 35 and the sliding plate 512. When the rotating column 51 rotates in the rotating groove 34, the sliding plate 512 can swing in the limiting groove 35.

[0032] According to the height of the clamping edges on the upper cover plate and the lower cover plate, the tilting angle of the lower module 31 is adjusted. When the height of the clamping edge is higher, the tilting angle of the lower module 31 is larger. The requirement for adjusting the tilting angle of the lower module 31 is that when the horizontally arranged lower cover plate and the clamping edge at one end of the upper cover plate are staggered, it is optimal that the other ends of the upper cover plate and the lower cover plate do not contact. Its shape is as shown in Figure 17 . Adjusting the tilting angle of the lower module 31 is to adjust the position of the height limiting plate 53 on the sliding plate 512. By adjusting the position of the sliding plate 512 relative to the rotating column 51, the rising distance of the rotating column 51 is regulated. After the distance between the height limiting plate 53 and the rotating column 51 is adjusted, the position of the height limiting plate 53 on the sliding plate 512 is fixed with screws. At the same time, the position of the thrust adjusting plate 54 on the rotating rod 56 is adjusted, that is, by adjusting the distance between the thrust adjusting plate 54 and the height limiting plate 53, the thrust of the top push spring 57 on the height limiting plate 53 is regulated, so that the height limiting plate 53 drives the rotating column 51 to push one end of the lower module 31. Among them, in order to prevent the weight of the lower module 31 from being too heavy for the top push spring 57 to push, the bottom of the lower module 31 is set as a frame structure to reduce the weight of the lower module 31. When the position of the thrust adjusting plate 54 is also adjusted, the rotating jacking member 5 can be used normally at this time.

[0033] During normal use, the pushing mechanism pushes the height limiting plate 53 and the rotating column 51 upward. The upward moving rotating column 51 jacks up the lower module 31. During the process of the lower module 31 being jacked up, the lower module 31 rotates upward around the position hinged to the bottom die shell 21, making the upper surface of the lower module 31 in an inclined state. Since the lower module 31 rotates, the moving track of the rotating groove 34 is an arc. And the rotating groove 34 is located below the hinged position of the lower module 31, so the rotating groove 34 moves obliquely upward away from the hinged position of the lower module 31 and the bottom die shell 21. During the movement of the lower module 31, the rotating groove 34 drives the rotating column 51 to move. During the movement of the rotating column 51, the sliding plate 512 slides inside the rotating plate 52, and the rotating plate 52 restricts one end of the sliding plate 512. At this time, the sliding plate 512 will tilt, causing the rotating column 51 to be driven by the sliding plate 512 to rotate in the rotating groove 34. And during the tilting process of the sliding plate 512, it will drive the rotating plate 52 to rotate on the mounting shell 55. That is, during the rotation of the lower module 31, the rotating column 51 drives the rotating lifting member 5 to rotate around the axis of the pin shaft. At this time, one end of the lower module 31 is jacked up, and the lower module 31 is in an inclined state. The staff places the upper cover plate and the assembly of the circuit board and the display screen mounted on the cover plate in the covering cavity.

[0034] Meanwhile, referring to Figure 6 , the upper die 4 includes an upper module 41 which is horizontally arranged. A pressing groove is formed at the bottom of the upper module 41. The edge of the lower cover plate is arranged in the pressing groove, and a suction cup 43 is arranged above the pressing groove. The suction cup 43 is connected to an air pump. When the lower cover plate is placed in the pressing groove, the air pump sucks air from the suction cup 43, and the suction cup 43 fixes the position of the lower cover plate in the pressing groove by suction. At this time, the lower cover plate is fixed under the upper module 41, and the clamping edge of the upper module 41 extends downward from the card slot, and its state is as Figure 16 shown.

[0035] Meanwhile, referring to Figure 6 and Figure 10 , a pressing groove 32 is formed on the upper side of the lower module 31 away from the position hinged to the bottom die shell 21. The pressing groove 32 is an inward concave arc. At the same time, a pressing strip 42 is fixed at the position corresponding to the pressing groove 32 on the lower side of the upper module 41. The pressing strip 42 protrudes from the lower side surface of the upper module 41. During the downward movement of the upper die 4, the pressing strip 42 first contacts the side wall of the pressing groove 32, and then by pressing the pressing groove 32 with the pressing strip 42, the lower module 31 rotates downward around the position hinged to the bottom die shell 21, and the lower module 31 gradually tends to be horizontal during the rotation.

[0036] When the upper die 4 descends, its state is as Figure 16 shown, the lower module 31 is in an inclined state, and the upper die 4 and the lower die 3 have not contacted yet; When the pressing strip 42 contacts the pressing groove 32, its state is asFigure 17 As shown, the caulking strip 42 contacts the pressing groove 32. At this time, the clamping plates of the upper cover plate and the lower cover plate have not contacted yet. As the upper mold 4 continues to move downward, the caulking strip 42 presses on the pressing groove 32, causing the lower module 31 to start rotating downward. During the downward rotation of the lower module 31, the clamping edges of the upper cover plate and the lower cover plate start to contact, and the buckles and slots at the contact position are engaged with each other. During the continuous downward movement of the lower module 31, the clamping edges of the upper cover plate and the lower cover plate gradually overlap and fit together. At this time, the buckles and slots of the overlapping clamping edges are engaged with each other. When the lower module 31 is in a horizontal state, all the buckles and slots on the upper cover plate and the lower cover plate are completely engaged. Its state is as Figure 18 shown. During the downward movement of the lower module 31, the sliding plate 512 slides downward in the rotating plate 52, and the height limiting plate 53 moves away from the rotating plate 52. During the process of the height limiting plate 53 moving away from the rotating plate 52, it squeezes the pushing spring 57, causing the pushing spring 57 to be further compressed.

[0037] By installing the upper cover plate on the lower mold 3 and the lower cover plate on the upper mold 4, it is convenient to position the upper cover plate and facilitate the installation between the upper cover plate and the lower cover plate. At the same time, the edge of the lower cover plate contacts the upper mold 4, and the middle part of the lower cover plate is adsorbed by the suction cup 43. When the lower cover plate is engaged with the upper cover plate, the middle part of the lower cover plate will not press on the circuit board and display screen in the upper cover plate, ensuring the effective engagement between the upper cover plate and the lower cover plate. At the same time, by rotating the lifting member 5 to lift one end of the lower mold 3 upward, the upper cover plate carried by the lower mold 3 is in an inclined state. When the upper mold 4 drives the lower cover plate to move downward, one end of the lower cover plate first contacts one end of the upper cover plate. As the upper mold 4 continuously moves downward and squeezes the lower mold 3, the lower mold 3 gradually tends to be in a horizontal state. During the process of the lower mold 3 tending to be in a horizontal state, the lower cover plate and the upper cover plate are engaged together. Through the progressive engagement design (engaging sequentially from one end to the other end), the assembly stress can be evenly dispersed, avoiding the situation where the cover plates are dented and bent due to instantaneous multi-point engagement on the upper cover plate and the lower cover plate, and ensuring the engagement effect between the upper cover plate and the lower cover plate.

[0038] After the stamping of the upper cover plate and the lower cover plate is completed, the suction cup 43 releases the adsorption of the lower cover plate and then moves upward to separate the upper mold 4 and the lower mold 3. During the upward movement of the upper mold 4, the rotating lifting member 5 pushes the lower module 31 upward. After the upper mold 4 and the lower mold 3 are separated, the lower module 31 returns to an inclined state.

[0039] After the upper mold 4 leaves the lower mold 3, the staff needs to take out the assembled intelligent learning machine. To facilitate the staff's taking, a buckle groove 33 is provided on one side of the cover placement cavity close to the pressing groove 32. The staff reaches out their hand from the buckle groove 33 to pick up the intelligent learning machine. When the outer frame of the intelligent learning machine is arc-shaped, the staff can pick up the intelligent learning machine through the arc-shaped surface. However, for the intelligent learning machine with a square frame, it is inconvenient for the staff to pick up the intelligent learning machine. To facilitate the staff to pick up different types of intelligent learning machines, please refer to Figures 11-15 , on the upper side of the rotating groove 34, there is a plug-in groove 37. Inside the plug-in groove 37, a jacking mechanism 36 is fixed. The jacking mechanism 36 includes a jacking plate 363 slidably arranged in the plug-in groove 37. On both sides of the jacking plate 363, there are respectively an upper hook plate 361 and a lower hook plate 362. A space for the jacking plate 363 to slide up and down is left between the upper hook plate 361 and the lower hook plate 362. At the same time, the upper hook plate 361 and the lower hook plate 362 are fixed in the plug-in groove 37 by screws. When the lower module 31 is in an inclined state, one end of the jacking plate 363 penetrates the side wall of the plug-in groove 37 and extends into the buckle groove 33. At the same time, a number of vertically arranged downward push springs 364 are installed on the jacking plate 363. The downward push springs 364 push the jacking plate 363 downward, so that one end of the jacking plate 363 does not extend out of the space formed by the upper hook plate 361 and the lower hook plate 362. An arc-shaped groove 511 is opened on the arc-shaped side wall of the rotating column 51. One end of the arc-shaped groove 511 is close to the axis of the arc-shaped groove 511 and the other end is far from the axis of the arc-shaped groove 511, that is, the arc-shaped groove 511 is inclined. One end of the jacking plate 363 is slidably arranged in the arc-shaped groove 511.

[0040] As shown in Reference 16, when the rotating jacking part 5 jacks up the lower module 31, that is, when the lower module 31 is in an inclined state, one end of the jacking plate 363 is located at a position far from the axis of the arc-shaped groove 511. One end of the jacking plate 363 extends upward, so that the jacking plate 363 jacks up one end of the upper cover plate in the cover placement cavity. Refer to Figure 18 As shown in the figure, when the lower module 31 is horizontally arranged, the arc-shaped groove 511 does not push the jacking plate 363. At this time, the downward push spring 364 pushes the jacking plate 363 downward, so that one end of the jacking plate 363 contacts the position close to the axis of the arc-shaped groove 511. At this time, the jacking plate 363 does not extend out of the jacking mechanism 36, so that the jacking plate 363 does not push the upper cover plate.

[0041] By setting the jacking mechanism 36 to jack up one end of the upper cover plate, when the lower mold 3 is inclined, the jacking mechanism 36 jacks up the upper cover plate, so that it is convenient for the staff to pick up and place the upper cover plate. When the upper cover plate and the lower cover plate are all engaged, the jacking mechanism 36 does not jack up the upper cover plate. In this way, the taking and placing of the cover plate are facilitated, and the trouble of the staff assembling the cover plate is reduced.
